Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2B16 (604 Variant) airplanes. This proposed AD was prompted by a report of sparking due to damaged wire insulation in the fueling adapter. This proposed AD would require inspecting the electrical wires attached to the airplane connector located behind the fuel scupper for damage, and all applicable related investigative and corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Comments Invited
The FAA invites you to send any written relevant data, views, or
arguments about this proposal. Send your comments to an address listed
under ADDRESSES. Include ``Docket No. FAA-2024-0467; Project Identifier
MCAI-2023-00892-T'' at the beginning of your comments. The most helpful
comments reference a specific portion of
[[Page 20142]]
the proposal, explain the reason for any recommended change, and
include supporting data. The FAA will consider all comments received by
the closing date and may amend the proposal because of those comments.
Except for Confidential Business Information (CBI) as described in
the following paragraph, and other information as described in 14 CFR
11.35, the FAA will post all comments received, without change, to
<a href="http://regulations.gov">regulations.gov</a>, including any personal information you provide. The
agency will also post a report summarizing each substantive verbal
contact received about this NPRM.
Confidential Business Information
CBI is commercial or financial information that is both customarily
and actually treated as private by its owner. Under the Freedom of
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public
disclosure. If your comments responsive to this NPRM contain commercial
or financial information that is customarily treated as private, that
you actually treat as private, and that is relevant or responsive to
this NPRM, it is important that you clearly designate the submitted
comments as CBI. Please mark each page of your submission containing
CBI as ``PROPIN.'' The FAA will treat such marked submissions as
confidential under the FOIA, and they will not be placed in the public
docket of this NPRM. Submissions containing CBI should be sent to
Steven Dzierzynski, Aviation Safety Engineer, FAA, 1600 Stewart Avenue,
Suite 410, Westbury, NY 11590; phone: 516-228-7300; email: <a href="/cdn-cgi/l/email-protection#7f46521e090c5211061e1c10521c100c3f191e1e51181009"><span class="__cf_email__" data-cfemail="4e77632f383d6320372f2d21632d213d0e282f2f60292138">[email protected]</span></a>. Any commentary that the FAA receives which is not
specifically designated as CBI will be placed in the public docket for
this rulemaking.
Background
Transport Canada, which is the aviation authority for Canada, has
issued Transport Canada AD CF-2023-55, dated July 18, 2023 (Transport
Canada AD CF-2023-55) (also referred to after this as the MCAI), to
correct an unsafe condition on certain Bombardier, Inc., Model CL-600-
2B16 (604 Variant) airplanes. The MCAI states that during airplane
refueling, a spark was seen when the fuel cap chain contacted one of
the fuel scupper bolts. An inspection was performed and one of the
fourteen bolts that surround the fuel inlet was found touching an
electrical wire behind the scupper. Due to vibrations during flight,
the bolt damaged the wire insulation and when the bolt was grounded to
the airframe a spark was generated. This condition, if not corrected,
could lead to electrical sparks during refueling and possibly result in
a fire.
The FAA is proposing this AD to address the unsafe condition on
these products. You may examine the MCAI in the AD docket at
<a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2024-0467.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Bombardier Service Bulletin 605-28-014, dated May
10, 2023; and Bombardier Service Bulletin 650-28-003, dated May 10,
2023. This service information specifies procedures for inspecting the
electrical wires attached to the J274 connector (i.e., the airplane
connector located behind the fuel scupper) for damage (i.e., core of
the electrical wire exposed, or damage such as black soot to the
insulation with no core exposure), and applicable related investigative
and corrective actions. The related investigative action includes
inspecting the fuel scupper for damage (i.e., arcing or pitting marks
directly or indirectly induced by the wire chaffed on the scupper bolt
and the surrounding area). The corrective actions include repairing any
damaged fuel scupper, repairing or replacing any damaged electrical
wire, and reinstalling the fuel scupper without a certain attachment
bolt. These documents are distinct since they apply to different
configurations of the airplane.
This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means identified in the ADDRESSES section.
FAA's Determination
This product has been approved by the aviation authority of another
country and is approved for operation in the United States. Pursuant to
the FAA's bilateral agreement with this State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI and
service information referenced above. The FAA is issuing this NPRM
after determining that the unsafe condition described previously is
likely to exist or develop on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in the service information already described.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 163 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
3 work-hours x $85 per hour = $255........................... $0 $255 $41,565
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need these on-condition actions:
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
4 work-hours x $85 per hour = $340 *.. ** $0 $340
------------------------------------------------------------------------
* The FAA has received no definitive data on which to base the cost
estimates for the on-condition scupper repair specified in this
proposed AD.
** The FAA has received no definitive data on which to base the parts
cost for the electrical wire replacement specified in this proposed
AD.
[[Page 20143]]
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs,
describes in more detail the scope of the Agency's authority.
The FAA is issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: General requirements.
Under that section, Congress charges the FAA with promoting safe flight
of civil aircraft in air commerce by prescribing regulations for
practices, methods, and procedures the Administrator finds necessary
for safety in air commerce. This regulation is within the scope of that
authority because it addresses an unsafe condition that is likely to
exist or develop on products identified in this rulemaking action.
Regulatory Findings
The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
have a substantial direct effect on the States, on the relationship
between the national Government and the States, or on the distribution
of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
